FEEDER FOR INGOT .MOLDS. A

Application filed January 27, 1923. Serial No. 815,319.

To all whom it may concern:

Be it known that BLooMFmLD l-l. HOWARD and ERNEST J TURNER, citizens ofthe United States, residing, respectively, at city ofWashington,District of Columbia, and Pittsburgh, county of Allegheny,State of Pennsylvania, have invented certain new and useful Improvementsin Feeders for Ingot .M0lds, of which the following is a specification.

Our invention relates to improvements in feeders for ingot molds.

The object of our invention is to provide a reversible sectional feederfor ingot molds,

having all of the advantages of the one piece feeder, to prevent seamsand holes known as piping and also'reduce segregation to a minimum.

Another object of our invention is to provide a sectional feeder whichcan be readily set up off of the mold and the several sections lockedtogether against lateral movement, the said looking means serving as asupport for the feeder, for holding it on the upper end of the moldpartly in the bore thereof and having means whereby the distance thefeeder enters the mold may be varied.

A further object of our invention is to provide a sectional feeder whichtakes up about one-fourth the space of the one piece feeder in shipmentand at the sametime there isless liability of the same breaking intransportation and the breaking of one section does not destroy theentire feeder and thus obviating the greater portion of the loss bybreaking in transportation.

, A still further object of our invention is to provide a simple, cheapand effective sectional mold feeder, having certain-details of structureand combination of parts hereinafter more fully set forth.

In the accompanying drawings,

Figure 1 is a perspective view of an ordinary ingot mold showing ourimproved sec tional feeder applied thereto.

Figure 2 is a sectional view of Figure 1 showing in dotted lines thefeeder in an inverted position.

Figure 3 is a transverse horizontal sectional view taken on the line 3-3Figure 2.

Figure 4 is a vertical sectional view simi lar to Figure 2 of a modifiedform of feeder, in which each edge of the sections is provided with twointerlocking members whereby the feeder can assume four differentpositions in respect to the mold, or any number of interlocking memberscan be used to suit the practice of the steel industry.

Figure 13 is a perspective view of an ingot mold showing the form offeeder shown in F igures 4i and 5 applied thereto and showing aretaining and strengthening band holdingthe sections together.

Figure 14;. is a side ele ation showing the mold in section and showingthe retaining and strengthening bands made of ordinary \VlIe.

Figure 15 is a side elevation similar to Figure 1% showing theinterlocking means broken off and the retaining and strengthening bandssupporting the feeder on the mold.

Referring now to the drawings 1 represents an ordinary ingot mold.having a square opening therein and in which is placed my improvedsectional feeder 2 which is of a shape to correspond with the opening inthe mold. The feeder 2 is made of four sections 3, 4c, 5 and 6, thesections a and 6 are of a width equal to the width of the opening in themold and the edges of these sections 7 are provided with square notches7 at a point intermediate the ends of the sections. The sections 3 and 5are of a width to fit in between the sections 4: and 6 and each edge isenter the notches 22 and 23.

provided with the rectangular lugs 8 of a size to snugly tit in therecesses 7 oi the sections t and 6 and are of a length greater than thethickness of the sections t and 6 whereby they extend out beyond theouter walls thereol and rest upon the upper edge of the ingot mold andsupports th feeder in the bore of the mold. The lugs 8 as shown inFigure 2 of the dra vings are nearer one end of the feeder than theother, so that by inverting the feeder, it will extend a shorterdistance in to the mold as shown in dotted lines Figure 2.

In the modification shown in Figures at to 7 inclusive we have showneach section 10 having each side edge provided with two uotcl'ies ll andi2 and each edeje of the section 10 having two lugs 13 and is adapted toenter the notches in the member 10 and said lugs forming supports forholding the feeder on the upper end of the mold, as described in respectto Figures 1 to 33 inclusive. The lugs 13 and 14 shown are diii'erentdistances from the cuts of the sections for a purpose which we willpresently describe. The lugs 13 and 14% are provided with horizontalnotches in their upper and lower faces as indicated at 16 and 17 whichweakens the lugs and allows that portion beyond the notches to bereadily broken off, so that there will be no projecting portion beyondthe outer wall of the feeder so that the feeder can enter the bore ofthe mold. As shown in Figure 4 of the drawings a considerable portion ofthe feeder extends into the mold but by inverting the feeder andallowing the upper lugs 13 to support it but a small portion of the"feeder will enter the mold. By breaking the upper lugs 13 of Figure 4when in an inverted position as shown in Figure 5, a greater portion ofthe feeder will enter the mold, than that shown in Figure l, or bybreaking ofi" the lower lugs 14 of Figure i, a still greater portion ofthe feeder will enter the mold.

In Figures 8. 9 and 10 instead of one section carrying the lugs and theother section having; the notches or recesses one edge of each sectionhas a notch or notches as the case may be as indicated at 18 and theother edge of the section having a lug or lugs 19 and the edges of thesections are mitered as indicated at 20 to prevent any inward movementof the sections, when on or oil of the mold, as clearly shown in Figures9 and 10 oi? the drawings.

ln l1 and 12 we have shown a round feeder and in which case it made oftwo sections but if desired could be made in three or more sectionswithout departing from our invention. In this form the section 21 hasboth edges tori 22 and 23 and the section 2 has its edges provided withthe lugs 25 and 26 adapted to As shown in the drawings these lugs do notfollow the contour of the sections and thus when the two sections arebrought together they will project beyond the wall of the sections andform projections to support the feeder on the mold. While we have shownthis arrangement or notches and lugs it will be understood hat the sameprinciple, as employed in Figures 8 to 10 inclusive could be used onthis round form.

in Figure 115 we have shown a that retaining and strengthening band 27extending around the mold between the lugs 13 and 14s and havii thetightening means 28 whereby the several sections forming the feeder maybe tightly held together.

in Figure Li inste d oi the flat retaining and strengthening band wehave shown two strancs or wire 29 which may have their ends twistedtogether or fastened in any desired i'i'ianner.

ln l igure we have shown the retaining band as means for supporting thefeeder on the mold. In this "form the ends of the that shown in Figure13.
